Design of Ground Radiation Antenna by using Compact EBG

Abstract

In this paper, design of ground radiation antenna using EBG technology for GPS applications. The compact electromagnetic band gap single cell is introduced in the middle of ground radiation and battery to reduce performance of ground radiation antenna due to huge battery. A minute loop-type circuit with 2.41-GHz Bluetooth, GPS applications is designed and it is comprised in the ground radiation antenna. By using meandering-line technology, a square split-ring resonator is constructed by changing compact EBG single cell. Efficiency of the proposed antenna is obtained as 90%at resonant frequency.
